In Texas, only cities--and not counties--have the authority to adopt zoning ordinances. If you are interested in finding out what type of zoning is in place for a particular address in a city, please call that city.

While Dallas County does not have the authority to enact zoning, it does have the authority to adopt various regu- lations or its unincorporated area (i.e., land that is not located within a city) which represents about ten percent of the land in Dallas County and which is primarily located in the County's southeastern corner.

The unincorporated area regulations that the County enforces govern:

all development within the floodplain

the subdivision of property

the installation of septic tanks

the construction and inspection of residential structures

certain outdoor businesses like junkyards, recycling businesses, and those that store or display merchandise outdoors

the location of communication facility structures such as cell towers

the construction of commercial buildings

DEVELOPMENT/FLOODPLAIN PERMITSDEVE

Most of the County's unincorporated area is considered to be in the floodplain. As a result, no development is allowed within the unincorporated area without a permit which either verifies that the development is not located within the floodplain or that it will be sufficiently elevated or protected from flooding. If you are interested in building on any of the land that is not located within a city, please call the County's Public Works Department at (214) 653-7151 to see how such a development permit can be obtained. Information pertaining to this permitting process is available at the bottom of this page.
